2'-O-MOE-A(Bz)-3'-phosphoramidite, also known as DMT-2'-O-MOE-rA(Bz) phosphoramidite, inserts 2'-O-methoxyethyl-modified adenosine into oligonucleotide phosphoramidites for antisense RNA. Its 2'-MOE backbone bolsters duplex stability, nuclease resistance, and has low toxicity, contributing to effective, safe genetic manipulation. It is an adenosine analog. Adenosine analogs mostly act as smooth muscle vasodilators and have also been shown to inhibit cancer progression. Its popular products are adenosine phosphate, Acadesine (HY-13417), Clofarabine (HY-A0005), Fludarabine phosphate (HY-B0028) and Vidarabine (HY-B0277).
